Symptom 10: Increased Heart Rate and Breathing
Lastly, we arrive at the final symptom in our RBD journey – increased heart rate and breathing. This symptom takes us beyond the realm of visible sleep behaviors, delving into the subtle physiological changes that occur during REM sleep in those with RBD.
Normal REM sleep is characterized by autonomic stability, with heart rate and breathing remaining relatively steady. However, in RBD, this calm is disrupted. The intense dreams and physical enactments can lead to surges in heart rate and rapid, shallow breathing.
These physiological changes are more than just transient fluctuations. They signify a heightened arousal state, indicative of the overactive REM sleep seen in RBD. This physiological arousal can contribute to the vivid dreams, physical enactments, and sleep disruptions that define RBD.
Moreover, chronic elevation of heart rate and alterations in breathing patterns can have long-term implications for cardiovascular and respiratory health. It’s, therefore, crucial to consider these physiological symptoms in the comprehensive management of RBD. (10)
